“What’s Wrong with Secretary Kim” is a romantic comedy that focuses on the relationship between Lee Young Joon (Park Seo Joon) and Kim Mi So (Park Min Young). Lee Young Joon is the narcissistic vice president of a company who has it all, while Kim Mi So is his secretary known for her competence.

In the released poster, Park Seo Joon and Park Min Young are posing exactly the same with both their arms and legs crossed. The two are dressed up in black formal suits as they look straight ahead, full of confidence.

Park Seo Joon perfectly embodies the character of a young leader. While his face is expressionless and serious, Park Min Young is smiling boldly with her hair pulled back.
